My previous Mountfield died after 20 years of great service, so no shock that I replaced it with another similar machine. But what a disappointment this machine is. It needs constant maintenance. In particular, the self propelled drive belt comes off too easily - you can fix by removing the battery, then the battery housing (there's a screw to remove, then lift and pull) and then you have access to the pulley. The build quality is poor. The engine is good. After 2 years the machine looks like it won't last another 3. Avoid.
